Bearing insert retaining means

ABSTRACT

BEARING INSERTS FOR CONNECTING RODS AND THE LIKE HAVE A SUBSTANTIALLY SEMI-CIRCULAR CONFIGURATION AND ARE ADAPTED TO BE INSERTED IN PAIRED RELATIONSHIP WITHIN A CONNECTING ROD AND CAP BORE WITH A RADIALLY LOOSE OR FLOATING FIT TO ALLOW RADIAL SELF-ADJUSTMENT OF THE BEARING INSERTS FOR OIL FILM CLEARANCE AND RESULTANT JOURNAL BEARING EFFECTS. THE BEARING INSERTS ARE RESTRAINED AGAINST AXIAL MOVEMENT OUT OF THE ROD BORE AND AGAINST ROTATIONAL MOVEMENT, PREVENTING LOADING OF THE BEARING JOINTS AND BACKS, AND ALLOWING BEARING DESIGNS ORIENTED TO LOAD PATTERNS, BY MEANS OF RESTRAINING TABS EXTENDING RADIALLY OUTWARDLY INTO APPROPRIATE NOTCHES IN THE ROD AND CAP BORES. THE TABS ARE PROVIDED BY SEGMENTS OF THE ENDS OF THE BEARING INSERTS WHICH ARE BENT OUTWARDLY FROM THE SURFACE OF THE BEARING. THE NOTCHES IN THE CONNECTING ROD AND CAP LOOSELY RECEIVE THE TABS AND PREVENT THEN AND THE BEARING INSERTS FROM MOVING AXIALLY OR ROTATING.

Grim, 710 Crestview Drive, Washington, Ill. 61571 Filed Mar. 16, 1971, Ser. No. 124,713 Int. Cl. F16c 9/00 US. Cl. 308-237 1 Sheet Drawing. 5 Pages Specification Bearing inserts for connecting rods and the like have a substantially semi-circular configuration and are adapted to be inserted in paired relationship within a connecting rod and cap bore with a radially loose or floating fit to allow radial self-adjustment of the bearing inserts for oil film clearance and resultant journal bearing effects.

The bearing inserts are restrained against axial movement out of the rod bore and against rotational movement, preventing loading of the bearing joints and backs, and allowing bearing designs oriented to load patterns, by means of restraining tabs extending radially outwardly into appropriate notches in the rod and cap bores.

The tabs are provided by segments of the ends of the bearing inserts which are bent outwardly from the surface of the bearing. The notches in the connecting rod and cap loosely receive the tabs and prevent them and the bearing inserts from moving axially or rotating.
